Europe fears a devastating crisis with ripple effects could erupt as Russia's war in Ukraine imposes a new blockade on the Black Sea, choking off a vital trade route.
The sense of alarm came to the fore on Wednesday during a meeting of EU foreign ministers in Ireland, marked by calls for an immediate ceasefire in the region.
"In the Black Sea, Russian strikes on grain ships could cause another worldwide food security shock," the EU's High Representative Kaja Kallas said.
Belgium's Maxime Prévot urged a "coordinated solution" to avert what he described as a threefold disaster: a collapse in Ukraine's state revenues, a global food crisis in Africa and an intensification of large-scale migration flows towards Europe.
"The blockages of grain and energy shipments in the Black Sea are not something we can simply watch from a distance either," he said.
Since July, Moscow has ramped up attacks on Ukraine's ports and vessels in the Black Sea, severely hampering its ability to sell grain to global clients such as Egypt, Algeria, Tunisia, Yemen and Indonesia, among others. Kyiv has responded in kind and launched drone and missile strikes against Russian ships and hubs.
The escalation has coincided with the peak of the harvest season in Ukraine and left scores of maize, barley and wheat piling up inside the country.
Before the renewed strikes, Ukraine exported 6 million tonnes of agricultural and steel products every month via three ports: Odesa, Chornomorsk and Pivdenny.
Now, it trades about 4.5 million tonnes via alternative routes as operators remain hesitant to undertake the dangerous sea voyage.
But these routes, also known as solidarity lanes, no longer benefit from a tariff-free regime, which Brussels abolishedafter backlash from Eastern European countries.
One of them, which connects Ukrainian exports to Romania's Port of Constanța via the Danube, is going through an unprecedented summer drought.
Bucharest has discussed logistical options with Kyiv to increase transit through the solidarity lanes, Romanian Foreign Minister Oana-Silvia Țoiu said in Ireland, expressing concern over the steady rise in global food prices.
"It is an essential instrument to allow proper access to affordable prices for grains across the Middle East and Africa," she said.
Her Ukrainian counterpart, Andrii Sybiha, who also participated in the meeting, urged Europeans to put "pressure" on Russia to achieve a full ceasefire in the Black Sea.
Sybiha said the alternative routes would never "compensate fully" exports by sea.
The virtual standstill at the ports has put local farmers under strain by raising transportation costs, depressing domestic prices and increasing the risk of bankruptcy as a new planting season begins. Storage is insufficient for the excess crops.
The steel industry has also been negatively impacted.
For Kyiv, a major cereals exporter, the financial shock is compounded by Russia's broader escalation, including relentless drone attacks designed to sow fear among civilians and disrupt economic activity in cities.
The country has already asked allies to help plug a €23 billion deficit, a gap that the Black Sea blockade threatens to exacerbate as public revenues diminish.
EU countries are currently considering amending the timeline of their €90 billion support loan to bring forward a share earmarked for 2027. But doing so would mean less money for next year and lead to an interruption of assistance.
While a group of countries is trying to revive the idea of tapping Russia's €210 billion immobilised assets, the European Commission is hesitant to reopen the contentious debate. Belgium, which holds the bulk of the assets, is staunchly opposed.
The Black Sea blockade also has global risks: a scarcity of cereals could drive inflation in developing countries, fuel popular discontent and encourage migration towards Europe. In Egypt, one of Ukraine's main clients, the price of bread is closely followed.
Migration has long been one of Europe's most contentious issues, but the debate has grown even more heated since the crisis in Ceuta, Spain, when more than 80,000 people crossed the border from Morocco in a mass influx.
These fears weigh heavily on Europeans, who have repeatedly accused Russia of weaponising food supply chains to undermine sympathy for Ukraine.
"Public opinion is growing weary of this support," Prévot said in Ireland, "yet it remains more essential than ever."
